Is This Galena ?


Recommended Posts


That is not a very good photo. I only see one area that makes me even remotely think it is galena. Galena breaks (cleaves) in a way that flat surfaces are the result. In the case of galena it is called perfect cubic cleavage so that you should see any broken areas on a piece of galena as flat surfaces unless the piece of galena has been eroded by water or sand. Your specimen appears to have many jagged, rough areas in the unfocused photo that do not appear to be flat surfaces resembling the faces of a cube except in one place. It should produce a lead gray streak on the rough side of a piece of white tile. So, I would not suspect galena.
